We have been using Zoom four 4 years now. And it has simplified conferences enormously. Sometimes a few of our customers insist on using their own corporate mandated systems. Half of these times there is a struggle to get the meeting going for one reason or the other. We offer to set up a zoom call and, quite literally, the call is back on track within 2 minutes. Regardless of which country the user is in, the device being used, or any other parameter which somehow seems to trip up all the other systems regularly.

I have used Skype, webex, hangout meet, gotomeeting, various other entirely web based ones and none come close to the reliability that Zoom provides. No wonder it's getting adopted like crazy.

Kudos to them for handling this traffic with absolutely no visible hiccups.
